IMPROVEMENT IN WINDOW-SASH STOPPERS.

Specification forming part of Letters Patent No. 39,513, dated August 11, 1863.

To all whom it may concern.-

Be it known that I, J AMES WARREN, of the city, county, and State of New York, now residing at No. 32 West Fortieth street, in said city, have invented a new and useful machine named a window-sash stopper, and used to retain the sash in any desired position and preventing the sash from shaking in any current of air; and I dohereby declare Vthat the following is ai'u1l,olear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in Which- Figure l represents the frame; Fig. 2, the entire machine in perspective; Fig. 3, the roller, the core, and its eye; Fig. 5, the sash in perspective, with the machine inserted on the one edge and strips of ivory on the other; Fig. 4, an end view of the sash with the ma chine and the ivory inserted.

rlhe frame, Fig. 1, is made of cast-iron or brass; letters A and B, the aperture for the reception of the roller, Fig. 3.

In Fig. 2, A A represent the frame; B, the

roller; C, the hood, and D the pin passing through the eye.

The combination of the whole of the abovedescribed machinery and its appropriation to the purposes herein specied.
